摘要
煤层在燃烧过程中,煤层上覆岩石受到高温烘烤,在磁性、导电性和温度等方面物理性质发生显著的变化,为磁法、自然电位法、测温法提供了理论基础。通过实例来说明综合物探方法对确定火烧区范围的有效性,并可优势互补、互相验证,提高物探解释精度。
In the process of coal combustion,the overlying rocks on the coal bed may have great changes in the physical features of magnetism,conductivity and temperature because of the high temperature of the fire,which gives theoretical bases for the magnetic method,the natural potential method and temperature measurement method.The paper explains the effectiveness of integrated geophysical methods in detecting the range of the self-igniting areas with examples,and they can complement and prove one another to improve the accuracy of geophysical detection.
